To all whom it may concern.

Be it known that a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,.have invented certain new and useful Improvements in Machines for Ap lying BottleCaps, of which the following 1s a specification.

This invention relates to improvements in th construction of the sealing head of such machine.

The invention contemplates the provision of a sealing machine whereby the cap is ap plied with the required pressure to effect an iermetic seal between the cork or other disk of elastic material in the cap andthe lip of the bottle or other like vcssel,and to lock the bottles flange of the cap into holding engagement with the shoulder or locking surface of the vessel.

In the drawings :.'Figure 1- is a side elevation of a machine of which my sealinghead may form a part; Fig. 2 is a central vertical section of the head with the parts inmormal position, a bottle cap being shown indotted lines in proper position in the seal cavity of the plunger; Fig; 3 is a similar view showing a capped bottle therein, the position they assume at the moment of locking the flange of the cap under the locking shoulder of the bottle; Fig. 4 is a plan view of the plunger, broken away to show the cap locking pins andthe means for holding the seals preparatory to their'application to the ig. 5 is-an end and side elevation of the pins, which operate the seal lockingdevices; Fig. 6 isan end elevation and plan of one of the seal locking ms or devices; and Fig. 7 is a detail sectiona view of a portion of the plunger, showing a means for normally retracting the seal locking pins.

Referring to the drawings, the numeral 1 designates the frame ofthe machine, with a broadened base 2, ends. tubular column 3 through which passes the head carrying vertically movable rod 4 which is suitably connect'ed with a treadle 5', by which the head may be depressed.

'he numeral 6- designa tes'aseat or support for the bottle.

The numeral 12 designates the plunger, circular in form to fit snugly in the bore of the lower part of the head, in which it is movable yertically. v

The underface of the plunger is inclined inwardly from the bottom as shown at 13, forming a continuation of the bottom line of the ledge 11, so that the bottle-will center itself correctly in the sealing cavity 14 in the center of the plunger. The upward movement of the bottle seal, in placi-n it in the plunger is limited 'by a threaded may be stationary or 1t may move vertically, upon, a rotatable carrien and brought at proper times to position to app'ly theseal as whose threads are received in the threads 16 of the inner Wall of the plunger, rendering the lug adjustable and thereby making it possililo to in effect, vary the sealing pressure, which is highly advantageous. The under face of the plug is cupped out as indicated at to conform to the dome or upper part of the head is especially adapted to apply has in its application a flaring action, I shghtly incline the wall of the seal cavity as indicated at 17 to permit this action. The numeral 18 designates a hollow extension ofthe lunger, upon which rests a flanged cap 19, etween which and the under face of the screw cap 10 is interposed the sealing spring 20 whlch holds the plunger normally seated on the ledge 11 of the part 9. Itis against the 1nunger moves forced downward.

vertlcally or yields in the sealing operation. Outside of this extension the plunger is provided with a series of sockets 21 that receive the cam pins 22, each formed with a cam surface 23 which co-acts with the cam or rounded surface 24 of a corresponding number of lockingpins 25, arranged in radial recesses 26, which recesses intersect the sockets 21. The recesses 26 extend from the eriphery of. the plunger whereby the seal ocking pins may-be readily inserted and a' thin wall 27 is left between the seal cavity and each recess, through which walls, I rovide' an opening 28, throu h which the re uced inner ends 28- of the sea locking pins extend when thepins are projected forward to indent and lock'the flange of the bottle seal under the locking shoulder on the bottle, .as will appear more clearly in a description of the operation which will be given later. i

The numeral29 designates a ring which surrounds the extension-18, which ring rests upon; a shoulder 30 in the lower part of the casing, and is provided with openings 31 for the assage of the cam pins 22. Each cam pin as a flange 32 that normally rests upon I the upper surface of the ring, whereby the downward movement of the pins is limited. Each cam pin is provided with a socket for the reception of a spiral spring 34, which springs bear upon the lower edge of the part 8 of the head casing, whereby the pins are As clearly shown in Fig.4, I provide between the seal locking ins a number of radially arranged springac'kedpins' 35, with their ends rojected slightlywithin the seal cavity. T 1688 are for the purpose of tern porarily holding the seal preparatory to the sealing operation. As shown in Fig. 7, I may .em loy light springs 36 for holding the seal loo zing pins normally retracted.

In operation, a seal is placed in cavity where it will be held by the pins 35. A bottle is placed upon the bottle support and the head depressed and when the sealing pressure is applied, thebottle will force the plunger upward-against the action of the sealing spring 20. This upward movement of the plunger will cause the cam surface of the pins 22 to yieldingly (due to the springs 34), engage the cam surfaces of the pins 25,

but the pins 25 are not, upon the initial 'movement of the plunger projected through the openings 28, but upon a further upward movement of the plunger, and when the required or desired sealing ressure has been applied'and the seal seate so that the lower portion of its flange is opposite the locking surface of the bottle, the cam surface of the pins 25 will have ridden downwardly against the cam surface of the pins 22, sufficiently to project the said pins 25 forward where their inner reduced ends indent the flange into firm locking engagement with the flange tion may be made within the spirit of this "invention, and while I have described the of the seal, forcing it under the head or loci;- ing shoulder'of the bottle. The pins 25 may be of such lengthand be capable of. suc

movement that they will be forced entirely into their recesses, as when the bottles to be capped are. uniform in'diameter, but it-will be seen that should a bottle be larger. than is usual, the pins would not be forced all the way into ther'ecesses, and the reaction resulting-from the engagement of the pins with the cap on such large bottle will be taken u automatically by t e springs 34, which wil be compressed somewhat and the cam sur: faces of the pins 25 will only ride upon the cam surfaces of the pins 22 a suflicient 'distance to yieldingly effect a lock and eliminate the danger of crushing the bottle. When the plunger returns to normalposition, the pins 22. will be forced downwardly by the springs 34, until their flanges rest upon the r ng 29, which obviously, imits the downward movement of the pins.

Modifications in the',described construc.-'

sealing head as especially adapted for aplying hard 'metal flanged 09. s" to bottles liavin an annular locking s ace or shoul-' der a jacent to their mouths, it will be understood that the heads would be equally adapted for applying caps or covers to ves sels other than bottles, such as' glass jars, cans, etc., it being obviously only necessary to vary the dimensions of the head partsto accommodate them to such additional uses.
